I agree that race is a social construct to some degree. For example, in America a person is considered "black" if he has one parent of African ancestry and one parent of European ancestry. However, I am not sure that the idea that "race is biologically meaningless" is defensible. I hope it is. But I wonder what we tell ourselves if the evidence says that it's not. I know you can tell where a person's ancestors recently came from based on their DNA, and that there are certainly distinct genetic lineages in the human population. I am open to reading more literature and articles on the subject. I am merely stating that according to the extent of my current knowledge, the idea that "race is meaningless" is suspect.
